CTICasesCPR-Related Thoracic Injuries
Imaging findings
CT demonstrates a large anterior chest wall hematoma, multiple buckled acute rib fractures with surrounding extrapleural hematomas (extrapleural fat sign), a displaced sternal fracture with anterior mediastinal hemorrhage, and pneumomediastinum (Macklin phenomenon) secondary to vigorous cardiopulmonary resuscitation (CPR).
Key takeaways
Cardiopulmonary resuscitation (CPR) can cause significant skeletal and soft tissue injuries in the chest, including rib fractures, sternal fractures, mediastinal hematomas, and pneumomediastinum. The Macklin phenomenon (alveolar rupture with dissection of air along bronchovascular sheaths into the mediastinum) is the typical mechanism for CPR-related pneumomediastinum.
